In this paper, a comparison of three high power single-phase power factor correction (PFC) pre-regulators is proposed. The topologies discussed are the boost converter, the interleaved boost converter and the dual boost converter. The control system used to perform the PFC is based in predictive current control laws and an algorithm to detect the conduction modes is also used, once the converters...
This paper investigates the problem of electromagnetic interference (EMI) generated into power converters used to correct the power factor (PFC). The topologies discussed in this paper are the boost converter, interleaved boost and dual boost. The paths traveled by differential mode (DM) noise and common mode (CM) noise are illustrated. An analysis of the inductor parasitic capacitance impact over...
The current harmonics injected in the mains by non-linear loads forced the use of pre-regulators to attend the IEC61000-3-2 standards and the CISPR22 recommendations. The increase of the switching frequency reduces the boost inductor volume, but requires a bulky EMI filter to operate according to the standards. Higher frequencies also intensify the switching losses in the semiconductor devices, increasing...
